Legal claims defining the scope of protection, as filed with the USPTO.
1. A method comprising: analysing an image intended for display on a transflective display to identify first pixels and second pixels in the image, said first pixels being reflective pixels in the transflective display, and the transflective display having a transmission mode and a reflection mode; creating an adapted image for display on the transflective display by changing reflectance of the first pixels relative to the second pixels by temporarily setting a color of the first pixels to black, and through spatial modulation of reflective pixels, but not of transmissive pixels, wherein reflective pixels are operational during the reflective mode and transmissive pixels are operational during the transmissive mode; and performing at least one of: storing the adapted image; forwarding the adapted image to a device; and using the adapted image to control the transflective display.
2. The method as claimed in claim 1 , further comprising: controlling the transflective display to display the adapted image.
3. The method as claimed in claim I, wherein creating the adapted image comprises reducing reflectance of the first pixels.
4. The method as claimed in claim 1 , wherein creating the adapted image comprises reducing reflectance of pixels associated with the reflection mode of the transflective display.
5. The method as claimed in claim 1 , wherein creating the adapted image comprises maintaining reflectance or transmittance of the second pixels.
6. The method as claimed in claim 1 , wherein creating the adapted image comprises independently controlling reflective pixels and transmissive pixels.
7. The method as claimed in claim 1 , further comprising: controlling the transflective display having physically distinct reflective pixels and transmissive pixels to display the adapted image.
8. The method as claimed in claim 1 , further comprising: controlling the transflective display in which the reflective pixels and transmissive pixels are combined via a transflector.
9. The method as claimed in claim 1 , wherein creating the adapted image comprises performing gamma correction on at least some of the first pixels.
10. The method as claimed in claim 9 , wherein the gamma correction is dependent upon a design of the transflective display.
11. The method as claimed in claim 9 , wherein the gamma correction is selective and is applied to a first sub-set of the first pixels but not to a second sub-set of the first pixels.
12. The method as claimed in claim 11 , wherein the second sub-set of the first pixels are selected to avoid clipping of the second sub-set of the first pixels as a consequence of gamma correction.
13. The method as claimed in claim 11 , wherein the selection is dependent upon detected ambient light at the transflective display.
14. The method as claimed in claim 1 , further comprising: performing gamma correction on at least some of the first pixels.
15. The method as claimed in claim 1 , wherein the creation of the adapted image is dependent upon whether the adapted image is monochrome or colored.
16. The method as claimed in claim 1 , wherein analysing the image comprises a pixel-by-pixel analysis of the image against a threshold.
17. An apparatus comprising: at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to perform: analyse an image intended for display on a transflective display to identify first pixels and second pixels in the image, said first pixels being reflective pixels in the transflective display, and the transflective display having a transmission mode and a reflection mode; create an adapted image for display on the transflective display by changing reflectance of the first pixels relative to the second pixels by temporarily setting a color of the first pixels to black, and through spatial modulation of reflective pixels, but not of transmissive pixels, wherein reflective pixels are operational during the reflective mode and transmissive pixels are operational during the transmissive mode; and perform at least one of: store the adapted image; forward the adapted image to a device; and use the adapted image to control the transflective display.
18. The apparatus as claimed in claim 17 , further comprising: the transflective display.
